[0057] It should be noted that the plurality of guide vanes 1201 are at least two guide vanes 1201, that is, the plurality of guide vanes 1201 can be two guide vanes 1201, three guide vanes 1201 or four guide vanes 1201 arranged in the front-rear direction, etc. It should also be noted that each guide vane comprises a plurality of guide vanes arranged at intervals in the circumferential direction, that is, the plurality of front guide vanes 121 are located in the same layer, and the plurality of rear guide vanes 122 are located in the same layer.

[0058] Specifically, the support 110 can provide a mounting position for the airflow adjusting piece 120, wherein the support 110 is provided with a ring-shaped air duct space 111, the plurality of front guide vanes 121 are arranged at intervals in the circumferential direction, a front gap is formed between every two adjacent front guide vanes 121 for airflow to pass through, the plurality of rear guide vanes 122 are arranged at intervals in the circumferential direction, a rear gap is formed between every two adjacent rear guide vanes 122 for airflow to pass through, and the front guide vanes 121 and the rear guide vanes 122 are arranged in the air duct space 111 in the axial direction, the front guide vanes 121 are located on the air outlet end of the rear guide vanes 122, airflow flows through the rear guide vanes 122 from the air inlet end of the rear guide vanes 122 and flows to the gap between the plurality of front guide vanes 121 through the air outlet end of the rear guide vanes 122, and the rear guide vanes 122 and the front guide vanes 121 can both play a role in guiding airflow, thereby playing a role in adjusting the flow direction of airflow.

[0059] Further, the airflow adjusting piece 120 has a first state and a second state, the plurality of front guide vanes 121 and the plurality of rear guide vanes 122 can move relatively to switch the airflow adjusting piece 120 between the first state and the second state, in combination with Figure 1 and Figure 2In the first state, the plurality of front guide vanes 121 and the plurality of rear guide vanes 122 are arranged one by one in the direction in which the central axis of the air duct space 111 extends, and at least part of the plurality of front guide vanes 121 and the plurality of rear guide vanes 122 overlap, i.e., the orthographic projection of the plurality of front guide vanes 121 in the direction of the central axis of the air duct space 111 at least partially overlaps the orthographic projection of the plurality of rear guide vanes 122 in the direction of the central axis of the air duct space 111, for example: the end of the plurality of front guide vanes 121 in the direction in which the central axis of the air duct space 111 extends can overlap the end of the plurality of rear guide vanes 122 in the direction in which the central axis of the air duct space 111 extends, or the plurality of front guide vanes 121 and the plurality of rear guide vanes 122 are arranged one by one.

[0060] When the plurality of front guide vanes 121 and the plurality of rear guide vanes 122 are arranged one by one, the front gap and the rear gap are arranged opposite to each other, the airflow flows into the rear gap, the rear guide vanes 122 guide the airflow, and the airflow continues to flow into the front gap, so that the front gap further guides the airflow, the circumferential component velocity of the airflow is converted into the axial component velocity, so that the airflow can be concentrated towards the central axis of the air duct space 111, the front gap and the rear gap form a continuous flow space, the front guide vanes 121 and the rear guide vanes 122 can continuously guide the airflow, continuously adjust the airflow, improve the flow regulation effect of the airflow adjustment member 120 on the airflow, improve the effect of converting the circumferential component velocity of the airflow into the axial component velocity, reduce the flow area of the airflow in the radial direction when the airflow flows out of the airflow adjustment member 120, so that the airflow after flowing out is in a cylindrical shape, and the axial velocity of the airflow when flowing out is large, so that the air outlet intensity is large.

[0061] It should be noted that the airflow flowing through the air type regulation mechanism 100 is spiral, which has a circumferential component velocity and an axial component velocity.

[0062] Further combining Figure 3 and Figure 4In the second state, in the central axis extension direction of the air duct space 111, the orthographic projection of each rear guide vane 122 is located between the orthographic projections of every two adjacent front guide vanes 121, that is, the rear guide vanes 122 are arranged opposite to the front gaps in the axial direction, so that the front guide vanes 121 and the rear guide vanes 122 are arranged staggered in the circumferential direction, the front gaps and the rear gaps are arranged staggered, the front guide vanes 121 and the rear guide vanes 122 cannot continuously guide the airflow, compared with the first state, the guiding time of the airflow by the rear guide vanes 122 when the airflow flows into the rear gaps is short, and similarly, the guiding time of the airflow by the front guide vanes 121 when the airflow flows into the front gaps is short, the overall rectification effect of the airflow by the airflow adjusting piece 120 is reduced, and the circumferential component velocity of the airflow can be maintained when the airflow flows through the airflow adjusting piece 120, so that the airflow presents a conical shape when flowing out of the airflow adjusting piece 120, and the divergence state of the airflow when flowing out is ensured.

[0063] It should be noted that the size of the front gap in the direction parallel to the central axis of the air duct space 111 is the length of the front gap, and the size of the rear gap in the direction parallel to the central axis of the air duct space 111 is the length of the rear gap.

[0064] In the related art, a guiding mechanism for adjusting the flow direction of the airflow is arranged on the fan, but the working state of the guiding mechanism cannot be adjusted, so that the blowing range and the air outlet feeling of the fan cannot be adjusted, which cannot meet the use demand of the user and affects the use experience of the user.

[0065] The airflow adjusting piece 120 is arranged, the airflow adjusting piece 120 is provided with the front guide vanes 121 and the rear guide vanes 122, in the first state, the front guide vanes 121 and the rear guide vanes 122 are arranged opposite in the front-rear direction, the front guide vanes 121 and the rear guide vanes 122 can continuously guide the airflow, the guiding effect of the airflow by the airflow adjusting piece 120 is improved, the effect of converting the circumferential component velocity of the airflow into the axial component velocity is improved, the flow area of the airflow in the radial direction when flowing out of the airflow adjusting piece 120 is reduced, and the axial velocity of the airflow when flowing out is large, the airflow is in a converging state when flowing out, and the air outlet intensity of the airflow is large; in the second state, the rectification effect of the airflow by the airflow adjusting piece 120 is small, the circumferential component velocity of the airflow can be maintained when the airflow flows through the airflow adjusting piece 120, so that the airflow can present a conical shape when flowing out of the airflow adjusting piece 120, and the divergence state of the airflow when flowing out is ensured, thereby, the blowing range and the air outlet intensity of the airflow by the air type regulation mechanism 100 are adjusted, the working state of the air type regulation mechanism 100 can be switched, the user can adjust the working state of the air type regulation mechanism 100 according to the actual use demand, different use demands of the user are met, and the structure of the air type regulation mechanism 100 is simple, which is beneficial to reducing the production cost of the air type regulation mechanism 100 and improving the production efficiency.

[0066] According to the air type regulation mechanism 100, the air type regulation mechanism 100 can adjust the air outlet range and the air outlet intensity by arranging the air flow adjusting piece 120. When the air flow adjusting piece 120 is in the first state, the front side guide vane 121 and the rear side guide vane 122 are arranged opposite to each other in the front-rear direction, the front side guide vane 121 and the rear side guide vane 122 can continuously guide the air flow, the circumferential component velocity of the air flow is converted into the axial component velocity, the air flow is in a converging state when flowing out, and the air outlet intensity of the air flow is large. In the second state, the air flow adjusting piece 120 has a small air flow rectification effect, the circumferential component velocity of the air flow can be maintained when the air flow flows through the air flow adjusting piece 120, the air flow can be in a conical shape when flowing out of the air flow adjusting piece 120, the diverging state of the air flow when flowing out is ensured, and the air flow adjusting piece 120 can be switched between the first state and the second state, so that the air type regulation mechanism 100 has different working states, the user can adjust the working state of the air type regulation mechanism 100 according to the actual demand to meet the use demand of the user, and the air type regulation mechanism 100 has a simple structure, which is beneficial to reduce the production cost of the air type regulation mechanism 100 and improve the production efficiency.

[0067] In combination with Figure 5 and Figure 6 , through simulation analysis of the air type regulation mechanism 100 of the present application, it is shown in B in Figure 5 and D in Figure 6 that in the first state, at the standard test distance, the air outlet range of the air type regulation mechanism 100 is 0.13㎡, and the average wind speed in the air outlet range is 2.02m / s. It is shown in A in Figure 5 and C in Figure 6 that in the second state, at the standard test distance, the air outlet range of the air type regulation mechanism 100 is 0.23㎡, and the average wind speed in the air outlet range is 1.36m / s.

[0068] It should be noted that the air outlet range refers to the area with a wind speed greater than 0.4m / s, and the “standard test distance” can be a distance of three times the diameter of the circle where the plurality of blade tips 311 are located, so as to facilitate simulation and test comparison of the air type regulation mechanism 100.

[0069] Of course, it can be understood that when the air type regulation mechanism 100 is simulated and tested, it is not limited to being measured at the above-mentioned “standard test distance”, as long as the air outlet effect of the air type regulation mechanism 100 in the first state and the second state is measured at the same position.

[0070] In combination with Figure 5 and Figure 6And the above data can be known that when the air type regulation mechanism 100 is in the first state, the air type regulation mechanism 100 has small air outlet range, high wind speed and strong air outlet, when the air type regulation mechanism 100 is in the second state, the air type regulation mechanism 100 has large air outlet range, low wind speed and soft air outlet, and the air feeling of the air type regulation mechanism 100 in different states has obvious difference, thereby improving the use experience of the user.

[0071] In combination Figures 1 to 4 And Figure 19 In some embodiments of the present application, a gap S is formed between the front guide vane 121 and the rear guide vane 122 in a direction parallel to the first central axis, and S < 3 mm. Further, the gap S is formed between the front guide vane 121 and the rear guide vane 122, and S ≤ 1.6 mm.

[0072] Specifically, under the premise of ensuring that the front guide vane 121 and the rear guide vane 122 do not collide, the smaller the gap between the front guide vane 121 and the rear guide vane 122 is, the better, so as to prevent the airflow from escaping from the gap between the front guide vane 121 and the rear guide vane 122, and to facilitate ensuring the wind gathering effect of the airflow adjusting piece 120.

[0073] Preferably, S is 0.5 mm, so as to prevent the airflow from escaping from the gap between the front guide vane 121 and the rear guide vane 122, and to effectively prevent the front guide vane 121 and the rear guide vane 122 from colliding when moving relative to each other, thereby ensuring the normal operation of the airflow adjusting piece 120.

[0074] In combination Figures 1 to 4 And Figure 19 In some embodiments of the present application, one end of the front guide vane 121 and the rear guide vane 122 opposite to each other is provided with a guide angle 1204 in a direction parallel to the first central axis.

[0075] Specifically, in the direction extending from the front guide vane 121 to the rear guide vane 122, the cross-sectional area of one end of the front guide vane 121 close to the rear guide vane 122 gradually decreases, and similarly, in the direction extending from the rear guide vane 122 to the front guide vane 121, the cross-sectional area of one end of the rear guide vane 122 close to the front guide vane 121 gradually decreases, so that the one end of the front guide vane 121 and the rear guide vane 122 opposite to each other is formed with the guide angle 1204, and the guide angle 1204 can effectively improve the smoothness of the airflow flowing in the airflow adjusting piece 120, and is conducive to reducing the noise generated by the airflow.

[0077] Specifically, the wind type regulation mechanism 100 is provided with the air duct 101, and the airflow can flow from the air inlet side of the air duct 101 to the air outlet side of the air duct 101, the air duct 101 can restrict the flow direction of the airflow, prevent the airflow from dispersing, and ensure the air outlet effect of the wind type regulation mechanism 100.

[0078] Further, the airflow adjusting part 120 is arranged in the air duct 101 to guide the airflow flowing into the air duct 101, wherein the airflow adjusting part 120 includes a plurality of guide vanes 1201, the plurality of guide vanes 1201 extend radially outward around the first center axis, and a gap is formed between every two adjacent guide vanes 1201, the airflow can flow through the guide vanes 1201 through the gap between the two adjacent guide vanes 1201, so that the guide vanes 1201 can guide the airflow to convert the circumferential component velocity into the axial component velocity, and the airflow can flow in the direction close to the first center axis.

[0079] Further combining Figure 1 And Figure 2 When the airflow adjusting part 120 is in the first state, the gap defined between every two adjacent guide vanes 1201 is the first airflow flow through interstice 1202, when the airflow adjusting part 120 is in the second state, the gap defined between every two adjacent guide vanes 1201 is the second airflow flow through interstice 1203, and in the direction parallel to the first center axis, the length of the first airflow flow through interstice 1202 is greater than the length of the second airflow flow through interstice 1203, that is, when the airflow adjusting part 120 is in the first state, the airflow flow through interstice of the airflow adjusting part 120 is lengthened, the airflow guiding time is long, the airflow adjusting part 120 has good rectification effect on the airflow, can improve the effect of converting the circumferential component velocity into the axial component velocity, so that the airflow converges in the direction close to the first center axis, and the airflow converging effect of the airflow adjusting part 120 on the airflow is realized.

[0080] Combining Figure 3 AndFigure 4 When the airflow adjusting piece 120 is in the second state, the airflow flows through the second airflow flow-through hole 1203, and since the length of the second airflow flow-through hole 1203 is relatively short, the airflow adjusting piece 120 has a short guiding time for the airflow, the guiding effect of the airflow adjusting piece 120 is reduced as a whole, and the circumferential component velocity of the airflow can be effectively maintained when the airflow flows through the airflow adjusting piece 120, so that the airflow presents a conical shape when the airflow flows out of the airflow adjusting piece 120, and the divergence state of the airflow is ensured.

[0088] When the airflow adjusting piece 120 is in the second state, each front side guide vane 121 and each rear side guide vane 122 are arranged in staggered positions in the direction parallel to the first central axis, so that each front side gap and each rear side gap are arranged in staggered positions in the direction parallel to the first central axis, each front side gap and each rear side gap are a second airflow flow-through aperture 1203, so as to realize that the number of the first airflow flow-through aperture 1202 is less than the number of the second airflow flow-through aperture 1203, the length of the second airflow flow-through aperture 1203 is short, and the front side guide vanes 121 and the rear side guide vanes 122 cannot continuously guide, compared with the first state, the overall rectification effect of the airflow adjusting piece 120 on the airflow is reduced, the airflow can maintain the circumferential component velocity when the airflow flows through the airflow adjusting piece 120, so that the airflow presents a conical shape when flowing out of the airflow adjusting piece 120.

[0089] The wind type regulation mechanism according to the embodiment of the utility model, including: air duct 101 and airflow adjusting piece 120, have the air inlet side and the air outlet side, air duct 101 restricts the airflow to blow out by the air inlet side to the air outlet side.

[0090] The airflow adjusting piece 120 is arranged in the air duct 101, for example, is located in the air duct outlet of the air duct 101, the airflow adjusting piece 120 has the first central axis, the airflow adjusting piece 120 includes a plurality of guide vanes 1201 that are spaced apart around the first central axis,

[0091] The plurality of front guide vanes 121 are located at the front side of the plurality of rear guide vanes 122 and can rotate relative to the plurality of rear guide vanes 122, the plurality of front guide vanes 121 are arranged at intervals in the circumferential direction, the plurality of rear guide vanes 122 are arranged at intervals in the circumferential direction, and a first airflow passage is defined between two adjacent front guide vanes 121, and a second airflow passage is defined between two adjacent rear guide vanes 122.

[0092] The airflow adjusting member 120 has a first state and a second state, in the first state, as shown in FIG. 1, the first airflow passage and the second airflow passage are correspondingly arranged to jointly guide the airflow to flow; that is, at least part of the plurality of front guide vanes 121 and the plurality of rear guide vanes 122 are arranged in an overlapping manner, the front guide vanes 121 and the rear guide vanes 122 can continuously guide the airflow, continuously adjust the airflow, improve the rectification effect of the airflow adjusting member 120 on the airflow, improve the effect of converting the circumferential component velocity of the airflow into the axial component velocity, reduce the flow area of the airflow in the radial direction when the airflow flows out of the airflow adjusting member 120, so that the airflow after flowing out presents a cylindrical shape as a whole, and the axial velocity of the airflow when flowing out is large, so that the air outlet intensity is large. Figure 2 In the second state, as shown in FIG. 2, the second airflow passage is arranged corresponding to the front guide vanes 121, and the front guide vanes 121 split the airflow flowing out of the second airflow passage. That is, the front guide vanes 121 and the rear guide vanes 122 cannot continuously guide the airflow, compared with the first state, the guiding time of the airflow by the rear guide vanes 122 when the airflow flows into the second airflow passage (rear gap) is short, similarly, the guiding time of the airflow by the front guide vanes 121 when the airflow flows into the first airflow passage (front gap) is short, the rectification effect of the airflow adjusting member 120 on the airflow is reduced as a whole, the airflow can maintain the circumferential component velocity when flowing through the airflow adjusting member 120, so that the airflow presents a conical shape as a whole when flowing out of the airflow adjusting member 120, and the divergence state of the airflow when flowing out is ensured.

[0094] Referring to

[0095] Figure 2 ​​In some embodiments of the utility model, the thickness of front guide vane 121 is H1, the thickness of rear guide vane 122 is H2, the sum of the thickness of front guide vane 121 and rear guide vane 122 is H3, and H3 satisfies: 10mm≤H3≤20mm.

[0096] Similarly, the "thickness of the guide vane" refers to the dimension of the guide vane in the axial direction.

[0097] Specifically, by making 10mm≤H3≤20mm, the guiding effect of airflow adjusting member 120 on the airflow is facilitated to be ensured, thereby facilitating to improve the adjusting effect of air type control mechanism 100 on the airflow. Preferably, H3 is 15mm, so as to reduce the occupied space of airflow adjusting member 120 while ensuring the adjusting effect of airflow adjusting member 120 on the airflow, thereby facilitating to reduce the volume of air type control mechanism 100.

[0098] When H3<10mm, the guiding effect of airflow adjusting member 120 on the airflow is poor, and when H3>20mm, the arrangement space required by airflow adjusting member 120 is large, resulting in large volume and weight of air type control mechanism 100, which is not conducive to the miniaturization and lightweight design of air type control mechanism 100.

[0099] It can be understood that the thickness H1 of front guide vane 121 can be the same as the thickness H2 of rear guide vane 122 and both are 7.5mm. By making the thickness of front guide vane 121 and rear guide vane 122 the same, the processing convenience of front guide vane 121 and rear guide vane 122 is facilitated, and the production and processing efficiency of air type control mechanism 100 is improved.

Fixing ring 112 has annular mounting space formed therein, and rotating ring 113 has annular arrangement space formed therein. The annular mounting space and the annular arrangement space are oppositely arranged in the axial direction. Front guide vane 121 can be mounted on fixing ring 112, and rear guide vane 122 can be mounted on rotating ring 113. Of course, it can be understood that front guide vane 121 can also be mounted on rotating ring 113, and rear guide vane 122 can be mounted on fixing ring 112, as long as front guide vane 121 and rear guide vane 122 can rotate relative to each other.

[0102] Further, the rotating ring 113 can rotate relative to the fixed ring 112, so that the front side guide vane 121 and the rear side guide vane 122 can rotate relative to each other, when it is needed to adjust the air outlet state, the rotating ring 113 can be driven to rotate, so that the front side guide vane 121 and the rear side guide vane 122 rotate relative to each other, the positions of the front side guide vane 121 and the rear side guide vane 122 are adjusted, so that the front side guide vane 121 and the rear side guide vane 122 are opposite to each other in the front-rear direction or the front side guide vane 121 and the rear side guide vane 122 are arranged in the circumferential direction, so as to adjust the working state of the air flow adjusting piece 120.

[0104] The guide vane support 1132 can be connected with the rotating ring 113 through a connecting rib structure, so as to guarantee the connection reliability between the guide vane support 1132 and the rotating ring 113, similarly, the guide vane support part 1121 can be connected with the rotating ring 113 through a connecting rib structure, so as to guarantee the connection reliability between the guide vane support part 1121 and the fixed ring 112.

[0105] With reference to Figure 11 In some embodiments of the utility model, the air type control mechanism 100 further includes a driving device, the driving device is connected in transmission with the rotating ring 113 to drive the rotating ring 113 to rotate, so as to realize the relative rotation of the front side guide vane 121 and the rear side guide vane 122, and adjust the working state of the air flow adjusting piece 120, wherein the driving device can realize the manual driving or automatic driving of the rotating ring 113.

[0106] Specifically, when the rotating ring 113 is manually driven, the driving device can be configured as a poking rod arranged on the rotating ring 113 and extending in a radial direction away from the central axis of the rotating ring 113, and a user can manually drive the poking rod to rotate the rotating ring 113 relative to the fixed ring 112, so as to realize the relative rotation of the front guide vane 121 and the rear guide vane 122, and enable the airflow adjusting piece 120 to switch between the first state and the second state, and realize the manual adjustment of the working state of the air type adjusting mechanism 100 by the user.

[0107] When the rotating ring 113 is automatically driven, a driving portion (not shown) is arranged on the rotating ring 113, and the driving device can be configured as a driving motor 140, and an output end of the driving motor 140 is connected with the driving portion to drive the rotating ring 113 to rotate.

[0108] For example, the output end of the driving motor 140 can be configured as a crank, the driving portion can be configured as a boss structure, the crank is connected with the driving portion, at this time, the rotating ring 113 can be a rocker in a four-bar mechanism, and a crank-rocker mechanism is formed between the crank and the rotating ring 113, when the driving motor 140 works, the crank drives the rotating ring 113 to perform a small-distance reciprocating rotation motion through the driving portion, so that the rotating ring 113 can rotate relative to the fixed ring 112, thereby enabling the front guide vane 121 and the rear guide vane 122 to rotate relative to each other.

[0109] Alternatively, the driving motor 140 can be configured as a swing motor, and the output end of the driving motor 140 can be configured as a connecting rod, and the driving portion can be configured as a connecting rod mounting column, the connecting rod is connected with the connecting rod mounting column, so that the output end of the driving motor 140 and the rotating ring 113 form a crank-rocker mechanism, and the rotating ring 113 is a rocker in the crank-rocker mechanism, when the driving motor 140 works, the connecting rod drives the rotating ring 113 to rotate through the driving portion, so that the front guide vane 121 and the rear guide vane 122 can rotate relative to each other, so that the front guide vane 121 and the rear guide vane 122 are arranged in one-to-one alignment or staggered in the front-rear direction, and automatic adjustment of the airflow adjusting piece 120 is realized.

[0110] Alternatively, the driving motor 140 can be configured as a stepping motor, and the output end of the driving motor 140 is provided with a driving gear, at this time, the driving portion is configured as a matching gear, the driving gear can be engaged with the matching gear, when the driving motor 140 works, the driving gear drives the matching gear to rotate to drive the rotating ring 113 to rotate, and the stepping motor reciprocates to drive the rotating ring 113 to reciprocate.

[0111] It can be understood that the driving device can be arranged on the outside of the rotating ring 113, or the driving device can also be arranged in the rotating ring 113, as long as the driving device can drive the rotating ring 113, and the specific arrangement manner is not limited herein.

[0112] In further embodiments of the present application, the guide vane support portion 1121 is provided with a driving motor 140 mounting position, and the driving motor 140 can be mounted in the guide vane support portion 1121. Correspondingly, the guide vane support 1132 is provided with a driving portion, which can be connected to the output end of the driving motor 140 to drive the rotation of the rotating ring 113.

[0113] Specifically, in combination with Figures 9 to 11 , the driving motor 140 can be configured as a swing motor, and the output end of the driving motor 140 is configured as a connecting rod, which extends in a radial direction after extending out of the guide vane support portion 1121. The guide vane support 1132 is formed with a avoiding slot 1133, and the connecting rod can be arranged in the guide vane support 1132 through the avoiding slot 1133, so as to connect the connecting rod with the driving portion. The avoiding slot 1133 can be configured as an arc-shaped slot.

[0114] In combination with Figures 9 to 11 , in some embodiments of the present application, the front guide vane 121 and the rear guide vane 122 are both formed in a circular arc shape.

[0115] Specifically, the cross section of the front guide vane 121 perpendicular to the central axis of the air duct space 111 is formed in a circular arc shape, and similarly, the cross section of the rear guide vane 122 perpendicular to the central axis of the air duct space 111 is also formed in a circular arc shape, so as to reduce the air resistance when the airflow flows through the front guide vane 121 and the rear guide vane 122, and ensure the flow effect of the airflow. Of course, it can be understood that the front guide vane 121 and the rear guide vane 122 can also be formed in other shapes, for example, in a straight line type.

[0116] In some embodiments of the present application, at least one layer of guide vanes 1201 rotates relative to the remaining layers of guide vanes 1201 within a set time period; or at least one layer of guide vanes 1201 reciprocatingly rotates relative to the remaining layers of guide vanes 1201 within a set time period.

[0117] Specifically, at least one layer of guide vanes 1201 can rotate counterclockwise or clockwise around the first central axis relative to the remaining layers of guide vanes 1201 within a set time period. Within the set time period, the guide vanes 1201 can rotate by a certain angle so that the multiple layers of guide vanes 1201 can be arranged in alignment or staggered in a direction parallel to the first central axis. The airflow adjusting member 120 can be switched from the first state to the second state or from the second state to the first state, so as to realize the automatic control of the working state of the airflow adjusting member 120.

[0118] Optionally, at least one layer of the guide vanes 1201 can reciprocate around the first central axis relative to the remaining layers of the guide vanes 1201 within a set time period, for example, at least one layer of the guide vanes 1201 can first rotate clockwise around the first central axis to a certain angle relative to the remaining layers of the guide vanes 1201 within a set time period, so that the multiple layers of the guide vanes 1201 can be arranged in alignment or misalignment in the direction parallel to the first central axis, and then the layer of the guide vanes 1201 rotates counterclockwise around the first central axis to realize resetting, so that the airflow adjusting member 120 can switch from the first state to the second state or from the second state to the first state, to realize automatic regulation of the working state of the airflow adjusting member 120.

[0119] It should be noted that the number of layers of the guide vanes 1201 and the number of layers of the rotating guide vanes 1201 are not specifically limited here, as long as the relative rotation between the multiple layers of the guide vanes 1201 can be ensured.

[0120] In combination Figures 1 to 4 In some embodiments of the utility model, the airflow adjusting member 120 is provided with a first central axis, and the multiple guide vanes 1201 are arranged at intervals around the first central axis; the air duct adjusting member 130 is further included in the wind type regulation mechanism 100, the airflow adjusting cavity 133 is formed in the air duct adjusting member 130, the inner wall of the airflow adjusting cavity 133 is deflected relative to the vertical plane of the first central axis under the action of the air duct adjusting member 130, the wind type regulation mechanism 100 has a wind gathering mode and a wind scattering mode, the inner wall of the airflow adjusting cavity 133 is deflected relative to the vertical plane at a larger angle in the wind scattering mode than in the wind gathering mode, so that the airflow is limited by the inner wall of the airflow adjusting cavity 133 in the wind gathering mode, and the airflow is guided outward by the inner wall of the airflow adjusting cavity 133 in the wind scattering mode and diffuses outward.

[0121] Specifically, when the airflow flows into the airflow adjusting member 120, the guide vanes 1201 can guide the airflow to adjust the air outlet effect when the airflow flows out of the airflow adjusting member 120, wherein the multiple guide vanes 1201 can be arranged in one layer, the multiple guide vanes 1201 are arranged at intervals around the first central axis, and the multiple guide vanes 1201 can be deflected relative to the first central axis, the guide vanes 1201 are deflected relative to the first central axis at a larger angle in the wind scattering mode than in the wind gathering mode, for example: in the wind gathering mode, the guide vanes 1201 can be arranged in parallel with the first central axis or at a slight angle, when the airflow flows into the airflow adjusting member 120 and hits the guide vanes 1201, the guide vanes 1201 can guide the airflow to converge in the direction of the first central axis; in the wind scattering mode, the guide vanes 1201 are deflected in the direction deviating from the first central axis, and the deflection angle of the guide vanes 1201 relative to the first central axis in the wind scattering mode is larger, the adjustment effect of the guide vanes 1201 on the airflow is reduced, and the airflow can maintain its circumferential component velocity, so that the airflow can be in a diverging state when it flows out of the airflow adjusting member 120.

[0122] Optionally, the plurality of guide vanes 1201 can be configured such that the length of the gap between every two adjacent guide vanes 1201 can be adjusted, and when in the wind gathering mode, the gap between every two adjacent guide vanes 1201 defines a first airflow flow-through aperture 1202, and when in the wind scattering mode, the gap between every two adjacent guide vanes 1201 defines a second airflow flow-through aperture 1203, and in the direction parallel to the first central axis, the length of the first flow-through aperture is greater than the length of the second airflow flow-through aperture 1203, that is, when in the wind gathering mode, the airflow guiding time of the airflow adjusting member 120 is long, the airflow adjusting member 120 has a good air flow rectification effect, which can improve the effect of converting the circumferential component velocity of the airflow into the axial component velocity, so that the airflow converges towards the first central axis, realizing the converging effect of the airflow adjusting member 120 on the airflow.

[0123] When in the wind scattering mode, the airflow flows through the second airflow flow-through aperture 1203, and since the length of the second airflow flow-through aperture 1203 is relatively short, the airflow guiding time of the airflow adjusting member 120 is short, the guiding effect of the airflow adjusting member 120 is reduced as a whole, and the airflow can effectively maintain its circumferential component velocity when flowing through the airflow adjusting member 120, so that the airflow flowing out of the airflow adjusting member 120 is in a conical shape, ensuring the divergence of the airflow.

[0124] Further, the air type regulation mechanism 100 further comprises an air duct adjusting member 130, and the air duct adjusting member 130 forms an airflow adjusting cavity 133 therein. When the airflow flows into the airflow adjusting cavity 133, the inner wall of the airflow adjusting cavity 133 can guide the airflow to adjust the air outlet feeling and air outlet range of the airflow flowing out of the air duct adjusting member 130. When adjusting the air duct adjusting member 130, the inner wall of the airflow adjusting cavity 133 formed by the air duct adjusting member 130 can be deflected relative to the vertical plane of the first central axis, so that the adjusting effect of the inner wall of the airflow adjusting cavity 133 on the airflow can be adjusted.

[0125] It should be noted that the "vertical plane" does not refer to a plane extending in the vertical direction, but only means perpendicular to the first central axis.

[0126] Further, the air type regulation mechanism 100 has a wind gathering mode and a wind scattering mode. When the air type regulation mechanism 100 is in the wind gathering mode, the inner wall of the airflow adjusting cavity 133 is arranged at an angle with the vertical plane, and the inner wall of the airflow adjusting cavity 133 can regularize the airflow, so that the circumferential component velocity of the airflow is converted into the axial component velocity, thereby causing the airflow flowing out of the air duct adjusting member 130 to converge towards the first central axis.

[0127] When the air type regulation mechanism 100 is in the air diffusion mode, the angle between the inner wall of the air flow adjusting part 120 and the vertical plane is larger than that when the air type regulation mechanism 100 is in the air convergence mode, so as to reduce the adjustment of the circumferential component velocity of the air flow by the inner wall of the air flow adjusting cavity 133, and the air flow can still maintain a certain circumferential component velocity when flowing out of the air duct adjusting part 130, so that the air flow as a whole presents a conical shape, and the air flow is in a divergent state.

[0128] In combination Figures 1 to 4 In some embodiments of the present application, the air duct adjusting part 130 is arranged on the support 110 and located at the air outlet side of the air flow adjusting part 120, and the area of the air outlet 131 of the air duct adjusting part 130 in the air convergence state is smaller than that in the air diffusion state.

[0129] It should be noted that the "air outlet side of the air flow adjusting part 120" refers to the side from which the air flow flows out of the air flow adjusting part 120.

[0130] Specifically, the air duct adjusting part 130 is arranged on the support 110, and the air duct adjusting part 130 is located at the air outlet side of the air flow adjusting part 120, the air flow flows into the air duct adjusting part 130 after flowing through the air flow adjusting part 120, and the area of the air outlet 131 of the air duct adjusting part 130 can be adjusted to further adjust the flow range of the air flow and the intensity of the air flow through the area of the air outlet 131.

[0131] When the air duct adjusting part 130 is in the air convergence state, the inner wall of the air duct adjusting part 130 can guide the air flow flowing therein, the air duct adjusting part 130 can regularize the air flow flowing therein, and the area of the air outlet 131 of the air duct adjusting part 130 is small, so that the air duct adjusting part 130 can adjust the circumferential component velocity of the air flow to an axial component velocity, so that the air flow flowing out of the air duct adjusting part 130 is more concentrated in the axial direction, the flow distance is longer, and the air flow is more powerful.

[0132] When the air duct adjusting part 130 is in the air diffusion state, the area of the air outlet 131 of the air duct adjusting part 130 is large, and the inner wall of the air duct adjusting part 130 has little interference with the circumferential component velocity of the air flow, so that the air flow can still maintain a certain circumferential component velocity when flowing out of the air duct adjusting part 130, so that the air flow flowing out of the air duct adjusting part 130 is more divergent in the radial direction, and the air flow is more gentle.

[0133] In combination Figure 1 And Figure 2 When the air flow adjusting part 120 is in the first state, the air duct adjusting part 130 is in the air convergence state, and the air duct adjusting part 130 can further regulate the air flow after the air flow flows out of the air flow adjusting part 120, so as to ensure the convergence effect of the air flow flowing out of the air flow regulation mechanism; in combination Figure 3 AndFigure 4 When the airflow adjusting piece 120 is in the second state, the air duct adjusting piece 130 is in the air diffusion state, and the air duct adjusting piece 130 can further maintain the velocity component of the airflow in the circumferential direction after the airflow flows out of the airflow adjusting piece 120, so as to ensure the divergence effect of the airflow flowing out of the air type regulation mechanism 100.

[0134] Therefore, by matching the air duct adjusting piece 130 with the airflow adjusting piece 120, the guiding effect of the air type regulation mechanism 100 on the airflow is improved, so as to improve the regulation effect of the air type regulation mechanism on the airflow, so that the air feeling of the outflow air has obvious differences, which is beneficial to meet different use requirements of users and improve the use experience of users.

[0135] In some embodiments of the utility model, the air duct adjusting piece 130 includes a plurality of swing leaves 132, and the plurality of swing leaves 132 are arranged along the circumferential direction of the support 110 of the air type regulation mechanism 100, and each swing leaf 132 is rotatably arranged on the support 110.

[0136] It should be noted that one end of the swing leaf 132 close to the support 110 in the axial direction is defined as the inner end of the swing leaf 132, which can also be understood as the air inlet end of the swing leaf 132, and the other end of the swing leaf 132 away from the support 110 in the axial direction is defined as the outer end of the swing leaf 132, which can also be understood as the air outlet end of the swing leaf 132, and the outer end of the swing leaf 132 is the outer side of the air duct adjusting piece 130, and the inner end of the swing leaf 132 is the inner side of the air duct adjusting piece 130, and in addition, the outer side of the air duct adjusting piece 130 forms the air outlet 131.

[0137] In combination with Figure 1 and Figure 3 , specifically, the swing leaf 132 is provided with a plurality of swing leaves 132, and the plurality of swing leaves 132 are uniformly arranged along the circumferential direction of the support 110, so as to construct the air duct adjusting piece 130 into a ring shape, the inner end of each swing leaf 132 is rotatably connected with the support 110, and when the inner end of the swing leaf 132 rotates relative to the support 110, the outer end of each swing leaf 132 can move towards or away from the central axis of the air duct adjusting piece 130, so as to adjust the area of the air outlet 131 of the air duct adjusting piece 130, so as to reduce or increase the area of the air outlet 131, so that the air duct adjusting piece 130 can be switched between the air diffusion state and the air concentration state.

[0138] It can be understood that when the inner end of the swing leaf 132 drives the outer end to rotate in the direction close to the central axis of the air duct adjusting piece 130, the plurality of swing leaves 132 shrink in the radial direction, the area of the air outlet 131 is small, the plurality of swing leaves 132 can regularize the airflow to convert the circumferential component velocity of the airflow into the axial component velocity, so that the air outlet intensity is large, the wind feeling is strong, and the air duct adjusting piece 130 realizes the air gathering state; when the inner end of the swing leaf 132 drives the outer end to rotate in the direction away from the central axis of the air duct adjusting piece 130, the plurality of swing leaves 132 expand in the radial direction, the area of the air outlet 131 increases, and the swing leaf 132 has small interference to the circumferential component velocity of the airflow. When the airflow is discharged from the air duct adjusting piece 130, the airflow can still maintain a certain circumferential component velocity, so that the air outlet area is large, the air outlet is soft, and the air duct adjusting piece 130 realizes the air diffusion state.

[0139] In combination Figure 2 and Figure 4 and Figure 9 and Figure 10 In some embodiments of the utility model, the rotating ring 113 is located at the air inlet end of the fixed ring 112, the front guide vane 121 is arranged on the fixed ring 112, the rear guide vane 122 is arranged on the rotating ring 113, and the air duct adjusting piece 130 is arranged on the fixed ring 112 and rotates in linkage with the airflow adjusting piece 120.

[0140] Specifically, as Figure 8 shown, the plurality of swing leaves 132 are arranged in sequence and at intervals in the circumferential direction, the air inlet end of the swing leaf 132 is provided with a driving seat 1321, and the side, away from the central axis of the air duct adjusting piece 130, of the driving seat 1321 is provided with a driving rod 1322, and the driving rod 1322 is rotatably connected with the driving seat 1321.

[0141] As Figure 9 shown, the air outlet end of the fixed ring 112 is provided with a plurality of swing leaf mounting parts 1122 arranged at intervals in the circumferential direction, the driving seat 1321 is rotatably connected with the swing leaf mounting part 1122, and the rotation axis between the driving rod 1322 and the driving seat 1321 is arranged in parallel with the rotation axes of the driving seat 1321 and the swing leaf mounting part 1122.

[0142] Further, as Figure 10 shown, the outer wall surface of the rotating ring 113 is formed with a plurality of driving blocks 1134 arranged at intervals in the circumferential direction, the driving blocks 1134 extend in the radial direction away from the central axis of the rotating ring 113, the driving blocks 1134 are formed with driving grooves 1135 recessed in the radial direction to the side of the central axis of the rotating ring 113, and the end of the driving rod 1322, away from the swing leaf 132, can be inserted into the driving groove 1135.

[0143] The drive groove 1135 extends obliquely on the drive block 1134, that is, one end of the drive groove 1135 is set close to the air outlet end of the rotating ring 113 in the axial direction, and the other end of the drive groove 1135 is set close to the air inlet end of the rotating ring 113 in the axial direction, and the multiple drive grooves 1135 are arranged in the same way.

[0144] Combination Figure 12 and Figure 13 When the rotating ring 113 rotates relative to the fixed ring 112, the drive rod 1322 can slide within the drive groove 1135. Since the drive groove 1135 is inclined, the drive rod 1322 moves axially towards or away from the air inlet end of the rotating ring 113 while sliding within the drive groove 1135. Specifically, the drive groove 1135 can drive the drive rod 1322 to move towards the air inlet end of the rotating ring 113. At this time, the drive rod 1322 drives the drive seat 1321 to rotate towards the air inlet end of the rotating ring 113, and simultaneously the drive seat 132... 1. The oscillating blades 132 are driven to rotate towards the air inlet end of the rotating ring 113. At this time, the air outlet ends of the multiple oscillating blades 132 move radially away from the central axis of the air duct adjustment component 130. The area of ​​the air outlet 131 of the air duct adjustment component 130 increases, and the air duct adjustment component 130 is in the air dispersion state. At the same time, the rotating ring 113 drives the rear guide blades 122 to rotate relative to the front guide blades 121, and rotates until the multiple front guide blades 121 and the multiple rear guide blades 122 are staggered one by one. The airflow adjustment component 120 is in the second state, and the wind pattern control mechanism 100 is in the air dispersion mode.

[0145] When the drive groove 1135 drives the drive rod 1322 to move away from the air inlet end of the rotating ring 113, the drive rod 1322 drives the drive seat 1321 to rotate away from the air inlet end of the rotating ring 113. At the same time, the drive seat 1321 drives the swing blades 132 to rotate away from the air inlet end of the rotating ring 113. At this time, the air outlet ends of the multiple swing blades 132 move radially closer to the central axis of the air duct adjustment component 130. The area of ​​the air outlet 131 of the air duct adjustment component 130 increases, and the air duct adjustment component 130 is in the air-gathering state. At the same time, the rotating ring 113 drives the rear guide blades 122 to rotate relative to the front guide blades 121, and rotates until the multiple front guide blades 121 and the multiple rear guide blades 122 are arranged one-to-one facing each other. The airflow adjustment component 120 is in the first state, and the wind pattern control mechanism 100 is in the air-gathering mode.

[0146] Combination Figure 12 and Figure 13In further embodiments of the present application, the fixing ring 112 is provided with a plurality of limiting boxes 1123 arranged in a circumferential direction, the limiting boxes 1123 extend in a radial direction away from the central axis of the fixing ring 112, the plurality of limiting boxes 1123 are arranged one-to-one corresponding to the plurality of swing leaf mounting portions 1122, the drive rod 1322 is arranged in the limiting box 1123 and is inserted into the drive slot 1135, the limiting box 1123 can limit the drive rod 1322 in the circumferential direction, preventing the drive rod 1322 from deforming during the driving process and affecting the driving effect of the swing leaf 132, and ensuring that the rotating ring 113 can effectively drive the swing leaf 132 through the drive rod 1322.

[0147] In combination Figures 1 to 4 In some embodiments of the present application, adjacent swing leaves 132 have overlapping areas in the circumferential direction of the support 110.

[0148] Specifically, the inner ends of the plurality of swing leaves 132 are arranged in sequence in the circumferential direction, and the adjacent swing leaves 132 can be arranged in an overlapping manner. For example, the swing leaves 132 can include a first swing leaf 1323, a second swing leaf 1324, and a third swing leaf 1325, and the first swing leaf 1323, the second swing leaf 1324, and the third swing leaf 1325 are arranged in sequence. In the arrangement direction of the plurality of swing leaves 132, one side of the first swing leaf 1323 can be overlapped on the second swing leaf 1324, and the side of the second swing leaf 1324 away from the first swing leaf 1323 can be overlapped on the third swing leaf 1325, so as to realize that adjacent swing leaves 132 have overlapping areas, to prevent air leakage of the air duct adjusting member 130 due to the gap between adjacent swing leaves 132, and to ensure the air outlet effect of the air type regulation mechanism 100.

[0149] In some embodiments, the swing leaf 132 is provided with seven swing leaves, and the width dimension H5 of the swing leaf 132 is between 80mm and 100mm, so as to ensure that there is an overlapping area between adjacent swing leaves 132. It can be understood that the number of swing leaves 132 and the size of the overlapping area between adjacent swing leaves 132 can be determined according to the size of the air type regulation mechanism 100, and are not limited herein.

[0150] The "width dimension of the swing leaf 132" refers to the maximum distance between two adjacent side wall surfaces between the air outlet end and the air inlet end of the swing leaf 132.

[0151] As Figure 2 shown, in some embodiments of the present application, in the air gathering state, the cross-sectional area of the airflow adjusting cavity gradually decreases in the direction towards the air outlet 131; and / or in the air dispersing state, the cross-sectional area of the airflow adjusting cavity gradually increases in the direction towards the air outlet 131.

[0152] Specifically, in the wind gathering state, the distance between the inner wall of the air duct adjusting piece 130 and the central axis thereof gradually decreases in the direction extending from the air flow adjusting piece 120 to the air duct adjusting piece 130 along the axial direction, that is, the air duct adjusting piece 130 gradually converges to the central axis thereof, so as to guide the air flow to gradually concentrate, which is beneficial to increasing the flow distance of the air flow in the air outlet direction and can enhance the intensity of the air flow, so that the air flow is more powerful when flowing out of the air type regulation mechanism 100.

[0153] It should be noted that the "inner wall" refers to the side wall surface of the air duct adjusting piece 130 close to the central axis thereof in the radial direction.

[0154] As shown in FIG. 1, specifically, in the wind gathering state, the distance between the inner wall of the air duct adjusting piece 130 and the central axis thereof gradually decreases in the direction extending from the air flow adjusting piece 120 to the air duct adjusting piece 130 along the axial direction, that is, the air duct adjusting piece 130 gradually converges to the central axis thereof, so as to guide the air flow to gradually concentrate, which is beneficial to increasing the flow distance of the air flow in the air outlet direction and can enhance the intensity of the air flow, so that the air flow is more powerful when flowing out of the air type regulation mechanism 100. Figure 4 Or, in the wind gathering state, the distance between the inner wall of the air duct adjusting piece 130 and the central axis thereof gradually decreases in the direction extending from the air flow adjusting piece 120 to the air duct adjusting piece 130 along the axial direction, and in the wind scattering state, the distance between the inner wall of the air duct adjusting piece 130 and the central axis thereof remains constant in the direction extending from the air flow adjusting piece 120 to the air duct adjusting piece 130 along the axial direction.

[0155] Or, in the wind gathering state, the distance between the inner wall of the air duct adjusting piece 130 and the central axis thereof remains constant in the direction extending from the air flow adjusting piece 120 to the air duct adjusting piece 130 along the axial direction, and in the wind scattering state, the distance between the inner wall of the air duct adjusting piece 130 and the central axis thereof gradually increases in the direction extending from the air flow adjusting piece 120 to the air duct adjusting piece 130 along the axial direction.

[0156] In some embodiments of the present application, each swing leaf 132 is formed as an arc-shaped plate.

[0157] Specifically, the plurality of swing leaves 132 are arranged in sequence in the circumferential direction, and each swing leaf 132 is formed as an arc-shaped plate, that is, in the radial direction, the inner side wall (that is, the side wall surface of the swing leaf 132 close to the central axis of the air duct adjusting piece 130 in the radial direction) of each swing leaf 132 is arc-shaped and protrudes away from the central axis of the air duct adjusting piece 130, so as to reduce the influence of the shape of the inner wall of the air duct adjusting piece 130 on the air flow, achieve the purpose of reducing the wind resistance, and ensure the flow effect of the air flow.

[0158] As shown in FIG. 1, specifically, in the wind gathering state, the distance between the inner wall of the air duct adjusting piece 130 and the central axis thereof gradually decreases in the direction extending from the air flow adjusting piece 120 to the air duct adjusting piece 130 along the axial direction, that is, the air duct adjusting piece 130 gradually converges to the central axis thereof, so as to guide the air flow to gradually concentrate, which is beneficial to increasing the flow distance of the air flow in the air outlet direction and can enhance the intensity of the air flow, so that the air flow is more powerful when flowing out of the air type regulation mechanism 100.

[0159] Figure 7 ​As shown, in some embodiments of the present invention, a guide portion 1326 is formed on the side of the oscillating blade 132 facing the central axis of the air duct adjuster 130, and the guide portion 1326 extends along the circumferential direction of the air duct adjuster 130.

[0160] Specifically, the oscillating blade 132 can be configured with a wider width at one end along the axial direction and a narrower width at the other end. The narrower end is defined as the inner end of the oscillating blade 132, which is rotatably connected to the support 110. The wider end is defined as the free end. A guide portion 1326 is provided on the oscillating blade 132. The guide portion 1326 is configured to protrude along the axial direction toward one side of the central axis of the support 110. The distance between the oscillating blade 132 at the guide portion 1326 and the central axis of the air duct adjustment component 130 is less than the distance between the oscillating blade 132 at other positions and the central axis of the air duct adjustment component 130.

[0161] Furthermore, when the airflow flows into the air duct regulating component 130, the circumferential velocity of the airflow flows into the air duct regulating component 130 and, under the action of the guide part 1326, it converges towards the central axis of the air duct regulating component 130. When the axial velocity of the airflow is low, the part of the airflow flowing along the circumferential direction converges along the axial direction, making the airflow flowing out of the air duct regulating component 130 more concentrated and the airflow stronger.

[0162] like Figure 3 As shown, in some embodiments of this utility model, the plurality of oscillating blades 132 include a main oscillating blade 1327 and a secondary oscillating blade 1328. The main oscillating blade 1327 and the secondary oscillating blade 1328 overlap at least partially. The main oscillating blade 1327 is adapted to drive the secondary oscillating blade 1328 to rotate relative to the bracket 110 through the overlap area, so that the area of ​​the air outlet 131 of the air duct adjustment component 130 is adjustable.

[0163] Specifically, the main swing blade 1327 can be connected to the rotating ring 113 for transmission. The rotating ring 113 drives the main swing blade 1327 to rotate relative to the support 110, so as to realize the outward opening and inward contraction of the main swing blade 1327. The main swing blade 1327 drives the secondary swing blade 1328 to rotate relative to the support 110 through the overlapping area, so as to realize the outward opening and inward contraction of the secondary swing blade 1328. This allows the area of ​​the air outlet 131 of the air duct adjustment component 130 to be adjusted, so that the air outlet range of the wind pattern control mechanism 100 is different, thereby meeting the different usage needs of users.

[0164] Combination Figure 2 and Figure 4 In some embodiments of this utility model, when the wind is gathered, the contraction angle of the blade 132 is less than or equal to 45°, and when the wind is dispersed, the expansion angle of the blade 132 is less than or equal to 45°.

[0165] Specifically, the angle between the axis of the oscillating blade 132 and the axis of the support 110 is α. When the oscillating blade 132 rotates and opens, the inner diameter of the air duct adjustment component 130 gradually increases. When the oscillating blade 132 rotates to the maximum position relative to the support 110, α ≤ 45°. This satisfies the function of pressurization and deceleration when the inner diameter of the air duct adjustment component 130 gradually expands, making the blown air gentle and smooth. It also avoids the airflow from being unable to flow through the air duct adjustment component 130 due to excessive pressure caused by an excessively large angle α, thereby preventing the airflow from losing its dynamic performance.

[0166] Furthermore, as the oscillating blade 132 rotates and retracts, the inner diameter of the air duct regulating component 130 gradually decreases. When the oscillating blade 132 rotates to its minimum position relative to the support 110, at this point, α ≤ 45°. This satisfies the function of pressure reduction and speed increase as the air duct regulating component 130 gradually retracts, resulting in a strong and concentrated airflow for rapid cooling. Simultaneously, it avoids an excessively large angle α that would cause the inner diameter of the air duct regulating component 130 to become too small, thus preventing a sharp increase in resistance and a sharp decrease in static pressure within the air duct regulating component 130, preventing airflow from failing to pass through it. Therefore, through the above design, the functionality of the airflow control mechanism 100 is improved, meeting different user needs.

[0167] Reference Figure 2 In some embodiments of this utility model, the length of the air duct adjustment component 130 is H4, where H4 > H3.

[0168] Specifically, "the length H4 of the air duct adjustment component 130" refers to the distance between the air duct adjustment component 130 at the air inlet end and the air outlet end.

[0169] The length of the air duct adjuster 130 is greater than the axial dimension of the airflow adjuster 120, so that the airflow travels a greater distance within the air duct adjuster 130 than the distance through the airflow adjuster 120. This is beneficial to improving the airflow guiding effect of the air duct adjuster 130, thereby improving the airflow adjustment effect of the wind pattern control mechanism 100.

[0170] In some embodiments of this utility model, H4≥40mm, and H4 / H3 satisfies: H4 / H3≥2.

[0171] Specifically, by ensuring that H4 ≥ 40 mm, the flow distance of the airflow within the duct adjustment component 130 is guaranteed, thereby improving the adjustment effect of the duct adjustment component 130 on the airflow. This is beneficial to improving the adjustment effect of the airflow control mechanism 100 on the airflow. Preferably, H4 is 40 mm, so that while ensuring the adjustment effect of the duct adjustment component 130 on the airflow, the space occupied by the duct adjustment component 130 can be reduced, which is beneficial to reducing the space occupied by the airflow control mechanism 100.

[0172] When H4 is less than 40 mm, the flow distance of the air flow in the air duct adjusting piece 130 is short, the air duct adjusting piece 130 has a poor adjusting effect on the air flow, and the difference in the air-out feeling is small, which affects the use experience of the user.

[0173] By designing the sizes of the air flow adjusting piece 120 and the air duct adjusting piece 130, H4 / H3 is greater than or equal to 2, which is beneficial to further improve the adjusting effect of the air type regulation mechanism 100 on the air flow and improve the difference in the air-out feeling.

[0174] In combination with Figure 9 and Figure 11 In some embodiments of the present application, the width of the front guide vane 121 and the rear guide vane 122 is L1, and 2 mm≤L1≤5 mm.

[0175] It should be noted that the "width of the front guide vane 121" refers to the distance between two adjacent side walls between the air inlet end and the air outlet end of the front guide vane 121, and the "width of the rear guide vane 122" refers to the distance between two adjacent side walls between the air inlet end and the air outlet end of the rear guide vane 122.

[0176] Specifically, 2 mm≤L1≤5 mm can meet the structural strength requirements of the front guide vane 121 and the rear guide vane 122, prevent the front guide vane 121 and the rear guide vane 122 from breaking, and at the same time, can reduce the space required for arranging the air flow adjusting piece 120 and reduce the weight of the air flow adjusting piece 120, thereby facilitating the lightweight design of the air type regulation mechanism 100.

[0177] In combination with Figures 1 to 4 According to the air type regulation mechanism 100 of the present application, the air duct 101 has an air inlet side and an air outlet side, and the air duct 101 limits the air flow to blow out from the air inlet side to the air outlet side. The air duct adjusting piece 130 is arranged at the air outlet side of the air duct 101, and the air duct adjusting piece 130 is provided with an air flow adjusting cavity 133. The air flow adjusting piece 120 is arranged opposite to the air flow adjusting cavity 133, and the air flow adjusting piece 120 is configured to adjust the air flow inside the air flow adjusting cavity 133. The air flow adjusting piece 120 has a first central axis. The inner wall of the air flow adjusting cavity 133 is deflected relative to the vertical plane of the first central axis under the action of the air duct adjusting piece 130 to adjust the air-out air flow of the outer ring of the air flow adjusting cavity 133, so that the air flow in the middle of the air flow adjusting cavity 133 is adjusted by the air flow adjusting piece 120 and the air flow of the outer ring of the air flow adjusting cavity 133 is adjusted by the air duct adjusting piece, and thus the air flow adjusted by the air flow adjusting piece 120 and the air flow adjusted by the air duct adjusting piece 130 can influence each other, thereby ensuring the air-out effect.

[0178] Further, the air type regulation mechanism 100 has a wind gathering mode and a wind scattering mode, the inner wall of the air flow regulation cavity 133 deflects a larger angle relative to the vertical plane in the wind scattering mode than in the wind gathering mode, so that the air flow is limited by the inner wall of the air flow regulation cavity 133 in the wind gathering mode, and the air flow diffuses outwardly guided by the inner wall of the air flow regulation cavity 133 in the wind scattering mode.

[0179] Specifically, the air type regulation mechanism 100 is provided with an air duct 101, the air flow can flow from the air inlet side of the air duct 101 to the air outlet side of the air duct 101, the air duct 101 can limit the flow direction of the air flow, prevent the air flow from diverging, and ensure the air outlet effect of the air type regulation mechanism 100.

[0180] It should be noted that the "first central axis" is parallel or collinear with the rotation central axis of the driving fan 300.

[0181] Further, the air duct regulation member 130 is located at the air outlet side of the air duct 101, when the air flow flowing in a spiral shape flows into the air flow regulation cavity 133, the inner wall of the air flow regulation cavity 133 can guide the outer peripheral air flow (i.e. the part of the air flow relatively close to the inner wall of the air flow regulation cavity 133), the air flow regulation member 120 is opposite to the air flow regulation cavity 133, the air flow regulation member 120 can guide the middle air flow (i.e. the part of the air flow relatively far away from the inner wall of the air flow regulation cavity 133) of the air flow flowing in a spiral shape flowing into the air flow regulation cavity 133, by cooperating the air duct regulation member 130 with the air flow regulation member 120, so as to ensure that the air type regulation mechanism 100 can adjust the whole air flow, improve the adjustment effect of the air type regulation mechanism 100 on the air flow, and be beneficial to improve the difference of the air outlet feeling in different modes. It should be noted that the air flow regulation member 120 can guide and adjust the air flow before flowing into the air flow regulation cavity 133, or the air flow regulation member 120 is arranged inside the air duct regulation member 130 to guide and adjust the air flow flowing into it.

[0182] Further, when adjusting the air duct regulation member 130, the inner wall of the air flow regulation cavity 133 formed by the air duct regulation member 130 can deflect relative to the vertical plane of the first central axis, so that the adjustment effect of the inner wall of the air flow regulation cavity 133 on the air flow can be adjusted.

[0183] It should be noted that the "vertical plane" does not mean a plane extending in the vertical direction, but only means a plane perpendicular to the first central axis.

[0184] Specifically, the wind type regulation mechanism 100 has a wind gathering mode and a wind scattering mode, when the wind type regulation mechanism 100 is in the wind gathering mode, the inner wall of the airflow adjusting cavity 133 is arranged at an angle with the vertical plane, and the inner wall of the airflow adjusting cavity 133 can regularize the airflow, so that the circumferential component velocity of the airflow is converted into the axial component velocity, thereby making the airflow out of the air duct adjusting piece 130 gather towards the direction close to the first central axis.

[0185] When the wind type regulation mechanism 100 is in the wind scattering mode, compared with the wind type regulation mechanism 100 in the wind gathering mode, the included angle between the inner wall of the airflow adjusting piece 120 and the vertical plane is larger, so as to reduce the adjusting effect of the inner wall of the airflow adjusting cavity 133 on the circumferential component velocity of the airflow, and the airflow out of the air duct adjusting piece 130 can still maintain a certain circumferential component velocity, so that the airflow out of the air duct adjusting piece 130 presents a conical shape as a whole, and the airflow is in a divergent state.

[0186] When the wind type regulation mechanism 100 is in the wind gathering mode, the air duct adjusting piece 130 is in a wind gathering state, and the airflow adjusting piece 120 is in a first state, so that the air duct adjusting piece 130 and the airflow adjusting piece 120 can both converge the airflow, thereby ensuring the wind gathering effect of the wind type regulation mechanism 100; when the wind type regulation mechanism 100 is in the wind scattering mode, the air duct adjusting piece 130 is in a wind scattering state, and the airflow adjusting piece 120 is in a second state, so that the air duct adjusting piece 130 and the airflow adjusting piece 120 can both diverge the airflow, thereby ensuring the wind scattering effect of the wind type regulation mechanism 100.

[0187] According to the wind type regulation mechanism 100 of the utility model, the airflow adjusting piece 120 and the air duct adjusting piece 130 are arranged, and the working states of the airflow adjusting piece 120 and the air duct adjusting piece 130 can be switched, so as to adjust the air outlet intensity and the air outlet range of the wind type regulation mechanism 100, in addition, the air duct adjusting piece 130 can cooperate with the airflow adjusting piece 120, so that the wind type regulation mechanism 100 can adjust the airflow as a whole, improve the adjusting effect of the wind type regulation mechanism 100 on the airflow, and the user can adjust the working state of the wind type regulation mechanism 100 according to the actual use demand, so as to meet the use demand of the user and improve the use experience of the user.

[0188] In combination Figures 1 to 4 In some embodiments of the utility model, the airflow adjusting piece 120 includes a plurality of guide vanes 1201 arranged at intervals around the first central axis, a first airflow flow gap 1202 is defined between adjacent guide vanes 1201 in the wind gathering mode, and a second airflow flow gap 1203 is defined between adjacent guide vanes 1201 in the wind scattering mode, in the direction parallel to the first central axis, the length of the first airflow flow gap 1202 is greater than the length of the second airflow flow gap 1203.

[0189] Specifically, the airflow adjusting piece 120 comprises a plurality of guide vanes 1201, the plurality of guide vanes 1201 extend radially outwardly around the first central axis, and a gap is formed between every two adjacent guide vanes 1201, the airflow can flow through the guide vanes 1201 through the gap between the two adjacent guide vanes 1201, so that the guide vanes 1201 can guide the airflow to convert the circumferential component velocity into the axial component velocity, and the airflow can flow towards the first central axis.

[0190] Further, when the wind type regulation mechanism 100 is in the wind gathering mode, the gap defined between every two adjacent guide vanes 1201 is defined as the first airflow flow aperture 1202, and when the airflow adjusting piece 120 is in the second state, the gap defined between every two adjacent guide vanes 1201 is defined as the second airflow flow aperture 1203, and in the direction parallel to the first central axis, the length of the first airflow flow aperture 1202 is greater than the length of the second airflow flow aperture 1203, that is, when the airflow adjusting piece 120 is in the first state, the airflow adjusting piece 120 has a long guiding time for the airflow, and the airflow adjusting piece 120 has a good flow regulating effect, which can improve the effect of converting the circumferential component velocity into the axial component velocity of the airflow, so that the airflow converges towards the first central axis, and the airflow adjusting piece 120 realizes the converging effect on the airflow.

[0191] When the wind type regulation mechanism 100 is in the wind scattering mode, the airflow flows through the second airflow flow aperture 1203, and since the length of the second airflow flow aperture 1203 is relatively short, the airflow adjusting piece 120 has a short guiding time for the airflow, the guiding effect of the airflow adjusting piece 120 is reduced as a whole, and the airflow can effectively maintain its circumferential component velocity when flowing through the airflow adjusting piece 120, so that the airflow presents a conical shape when flowing out of the airflow adjusting piece 120, and the divergence state of the airflow is ensured.

[0192] It should be noted that the first central axis is parallel to or collinear with the rotation center line of the driving fan 300.

[0193] In combination with Figure 15 and Figure 16 , the fan 1000 according to the present application comprises a wind type regulation mechanism 100 and a driving fan 300, the wind type regulation mechanism 100 is the wind type regulation mechanism 100 described above, and the driving fan 300 is located at the air inlet side of the airflow adjusting piece 120.

[0194] It should be noted that the side of the airflow adjusting piece 120 away from the air duct adjusting piece 130 in the axial direction is defined as the air inlet side of the airflow adjusting piece 120.

[0195] Specifically, the driving fan 300 drives the air to form an air flow, the air flow flows through the air flow adjusting piece 120 and the air duct adjusting piece 130 in turn, the air flow adjusting piece 120 and the air duct adjusting piece 130 guide the air flow, and the air flow flows out of the fan 1000 after flowing out of the air duct adjusting piece 130, so as to realize the air supply of the fan 1000.

[0196] Since the fan 1000 is provided with the air type regulation mechanism 100, the air flow adjusting piece 120 and the air duct adjusting piece 130 are arranged, and the working state of the air flow adjusting piece 120 and the air duct adjusting piece 130 can be switched to adjust the air supply strength and the air supply range of the air type regulation mechanism 100. In addition, the air duct adjusting piece 130 can cooperate with the air flow adjusting piece 120, so that the air type regulation mechanism 100 can adjust the whole air flow, improve the adjustment effect of the air type regulation mechanism 100 on the air flow, and the user can adjust the working state of the air type regulation mechanism 100 according to the actual use demand, so as to meet the use demand of the user and improve the use experience of the user.

[0197] In combination with Figure 12 , Figure 13 and Figure 17 , the fan 1000 is provided with a shell 200, the shell 200 is provided with an air inlet area 210 and an air outlet area 220, and the air type regulation mechanism 100 and the driving fan 300 can be arranged in the shell 200.

[0198] Specifically, the shell 200 is configured as a cylindrical structure with a cavity, the shell 200 can serve as a mounting carrier of the driving fan 300 and the air type regulation mechanism 100, the driving fan 300 and the air type regulation mechanism 100 can be mounted in the shell 200, and the shell 200 can protect the driving fan 300 and the air type regulation mechanism 100, avoiding damage to the fan 1000 due to foreign matter entering the driving fan 300 or the air type regulation mechanism 100.

[0199] Further, the rear side of the shell 200 is formed with the air inlet area 210, and the external air enters the shell 200 through the air inlet area 210. The front side of the shell 200 is formed with the air outlet area 220, which can be configured as an opening formed on the front side of the shell 200. The driving fan 300 and the air type regulation mechanism 100 can be mounted in the shell 200 through the air outlet area 220, so as to facilitate the assembly of the fan 1000, and the air flow flows out of the fan 1000 through the air outlet area 220 after flowing out of the air duct adjusting piece 130, so as to realize the air supply of the fan 1000.

[0200] Optionally, the driving fan 300 can be arranged outside the shell 200, and the arrangement mode of the driving fan 300 can be determined according to the actual installation demand of the fan 1000, which is not limited here.

[0201] As Figure 17 shown, in some embodiments of the present application, when the rotating ring 113 is provided with a toggle lever, the shell 200 is provided with a through hole 230, the toggle lever is arranged in the through hole 230 and can slide in the through hole 230.

[0202] Specifically, the through hole 230 is configured as an elongated circular hole extending along the circumferential direction of the shell 200, and the user can drive the toggle lever to slide in the through hole 230, thereby achieving the rotation of the rotating ring 113 relative to the bracket 110 by the toggle lever.

[0203] In some embodiments of the present application, a driving device support is further arranged in the shell 200, and when the driving device is arranged outside the bracket 110, the driving device support is used to install and support the driving device.

[0204] In some embodiments of the present application, the wind type control mechanism 100 is detachably connected with the shell 200.

[0205] Specifically, referring to Figure 17 , the bracket 110 is provided with a plurality of bracket mounting seats 114 arranged at intervals in the circumferential direction, and the shell 200 is provided with a plurality of bracket fixing seats 240 arranged in the circumferential direction of the shell 200, when the wind type control mechanism 100 is installed in the shell 200, the plurality of bracket mounting seats 114 and the bracket fixing seats 240 are arranged one by one, and threaded holes are formed on the bracket mounting seat 114 and the bracket fixing seat 240, and the threaded connection member can be arranged in the threaded hole and connected the bracket mounting seat 114 and the bracket fixing seat 240, so that the wind type control mechanism 100 is connected with the shell 200, thereby realizing the detachable connection of the wind type control mechanism 100 and the shell 200, facilitating the disassembly, maintenance or replacement of the wind type control mechanism 100.

[0206] Optionally, the air inlet end of the bracket 110 can be provided with a bracket ball head extending in the axial direction, and the bracket ball head can be provided with two, the two bracket ball heads are arranged at intervals in the radial direction, and the shell 200 can be provided with a sliding groove, the bracket ball head can be inserted in the sliding groove at a certain angle, and the bracket 110 and the shell 200 can be fixed by rotating, when the wind type control mechanism 100 needs to be detached from the shell 200, the bracket ball head can be pulled out from the sliding groove by reversing rotation.

[0207] Optionally, the air inlet end of the bracket 110 can be provided with an external thread, and the inner side of the shell 200 can be formed with an internal thread, and the bracket 110 and the shell 200 can be detachably connected by threaded connection, facilitating the disassembly of the wind type control mechanism 100.

[0208] Optionally, the air inlet end of the support 110 can be provided with a magnet seat, and the inner side of the shell 200 can be provided with a matching magnet, the magnet seat can be matched with the matching magnet by magnetic attraction, so that the air type regulation mechanism 100 is installed in the shell 200, and the support 110 and the shell 200 are assembled by magnetic attraction, so that the air type regulation mechanism 100 is convenient to disassemble and assemble.

[0209] In some embodiments of the utility model, the driving fan 300 is an axial flow fan.

[0210] Specifically, the driving fan 300 is an axial flow fan, the blades 310 of the driving fan 300 extend in a radial direction, when the plurality of blades 310 rotate, the air on the side of the blades 310 away from the airflow adjusting piece 120 is driven to flow to the airflow adjusting piece 120 to form an airflow, and the blades 310 can guide the airflow when the airflow flows through the blades 310 to form an oblique airflow, at this time, the airflow has a component speed in the axial direction and a component speed in the circumferential direction.

[0211] Further, the airflow adjusting piece 120 and the air duct adjusting piece 130 can guide the airflow, wherein when the airflow adjusting piece 120 is in the second state, the air duct adjusting piece 130 is in a wind dispersing state, the airflow adjusting piece 120 and the air duct adjusting piece 130 have small interference to the airflow, and the airflow can still maintain a certain circumferential component speed when the airflow flows out of the air type regulation mechanism 100, so that the airflow flowing out of the air type regulation mechanism 100 is more gentle in the radial direction.

[0212] When the airflow adjusting piece 120 is in the first state, the air duct adjusting piece 130 is in a wind concentrating state, the airflow adjusting piece 120 guides the airflow after the airflow hits the airflow adjusting piece 120, the circumferential component speed of the airflow is converted into an axial component speed, and the airflow further flows into the air duct adjusting piece 130 after flowing through the airflow adjusting piece 120, the air duct adjusting piece 130 further regulates the airflow flowing therein, so that the airflow flowing out of the air duct adjusting piece 130 is more concentrated in the axial direction.

[0213] In combination Figures 1 to 4 In some embodiments of the utility model, the cross section of each guide vane 1201 is formed as a curve, the curve is an Archimedes spiral, the bending direction of the curve is opposite to the rotation direction of the blades 310 of the driving fan 300, and the cross section is perpendicular to the rotation center line of the driving fan 300.

[0214] Specifically, the rotation center line of the driving fan 300 is arranged in line with the central axis of the support 110, the front guide vane 121 and the rear guide vane 122 are of the same structure, and the front guide vane 121 is taken as an example for description. The cross section perpendicular to the rotation center line of the driving fan 300 is formed as an Archimedes spiral, and the bending direction of the curve (i.e. the rotation direction of the Archimedes spiral) is opposite to the rotation direction of the blade 310 of the driving fan 300. The rotation direction of the blade 310 of the driving fan 300 is the same as the direction of the tangential velocity of the airflow in the circumferential direction. In this way, after the airflow flows through the airflow adjusting member 120 and contacts the airflow adjusting member 120, the airflow can move along the wall surface of the front guide vane 121 (or the rear guide vane 122) towards the central axis of the support 110. The airflow can converge towards the central axis of the support 110, thereby facilitating the increase of the axial velocity of the airflow and the reduction of the air outlet area of the airflow in the radial direction, so that the air outlet is strong.

[0215] As shown in FIG. 1, the first projection plane is perpendicular to the central axis of the support 110. Figure 16 As shown in FIG. 1, the first projection plane is perpendicular to the central axis of the support 110.

[0216] Specifically, the plurality of blades 310 are arranged in sequence in the axial direction, and the driving fan 300 drives the plurality of blades 310 to rotate when in operation. The blades 310 drive the surrounding airflow to flow in the process of rotation, thereby forming an airflow with a certain flow rate.

[0217] It should be noted that the "first projection plane" can be understood as a projection plane in the front-rear direction or the thickness direction of the fan 1000.

[0218] Further, the airflow generated by the rotation of the blade 310 can flow into the air duct space 111. In the first projection plane, the outer edge of the orthographic projection of the air duct space 111 can be arranged around the outer circumferential side of the circle where the blade tips 311 of the plurality of blades 310 are located, or the orthographic projection of the support 110 just coincides with the above-mentioned circle, which is beneficial to make the airflow generated by the blade 310 blow to the air duct space 111, thereby facilitating the airflow generated by the blade 310 to flow through the airflow adjusting member 120, preventing the airflow from diverging inside the fan 1000, and effectively concentrating the airflow.

[0219] It should be noted that in the radial direction, the position farthest from the hub of the driving fan 300 is defined as the blade tip 311 of the blade 310.

[0220] The "in the first projection plane, the orthographic projection of the air duct space 111 covers the circle where the blade tips 311 of the plurality of blades 310 are located" in the present application can refer to the outer edge of the orthographic projection of the air duct space 111 and the above-mentioned circle just coincides, or can refer to the outer edge of the orthographic projection of the air duct space 111 is located outside the above-mentioned circle (i.e. the above-mentioned circle falls into the orthographic projection of the air duct space 111).

[0221] With reference to Figure 16 , a part of the blades 310 of the driving fan 300 extends into the air duct space 111.

[0222] Specifically, the size of the air duct space 111 in the radial direction can be greater than the radial size of the circle where the blade tips 311 of the plurality of blades 310 are located, and a part of the blades 310 extends into the air duct space 111, the blades 310 rotate in the air duct space 111 and generate airflow, the inner wall surface of the support 110 can guide the airflow into the air duct space 111, and the inner wall surface of the support 110 can limit the flow of the airflow, prevent the airflow from being dispersed before flowing into the air duct space 111, and ensure the flow efficiency of the airflow.

[0223] It can be understood that the end of the blade 310 in the axial direction can be arranged in the air duct space 111, or the blade 310 can be arranged in the air duct space 111 entirely, and the arrangement of the blade 310 can be determined according to the size of the fan 1000 as a whole, the blade 310 and the support 110, which is not limited here.

[0224] With reference to Figure 16 , in the direction parallel to the rotation center line of the driving fan 300, the distance between the blade 310 of the driving fan 300 and the air inlet end of the airflow adjusting member 120 is L2, 7mm≤L2≤15mm.

[0225] Specifically, 7mm≤L2≤15mm so that the airflow generated by the rotation of the blade 310 flows to the airflow adjusting member 120, which can prevent the risk of mutual interference between the blade 310 and the airflow adjusting member 120 due to the too small distance between them, and can avoid the airflow from being dispersed in the housing 200 due to the too large distance between the blade 310 and the airflow adjusting member 120, which ensures the flow effect of the airflow, guarantees the outflow air feeling, and can make the structure of the fan 1000 compact, reduce the size of the fan 1000 in the axial direction, and preferably L2 is 10mm.

[0226] With reference to Figure 16In some embodiments of the utility model, on the first projection surface, the diameter of the circle where the blade tip 311 of the plurality of blades 310 is located is D, and the size of the blade 310 in the direction parallel to the central axis of the driving fan 300 is defined as the height size H6 of the blade 310, wherein D = 180mm, H6 = 80mm, so as to improve the ability of the blade 310 to drive airflow, improve the flow efficiency and strength of the airflow, and thus improve the air feeling of the fan 1000.

[0227] Referring to Figure 14 , through simulation analysis of the air type regulation mechanism 100 provided with the air duct adjusting piece 130 and the airflow adjusting piece 120, the blowing range of the fan 1000 in the scattering mode is greater than the blowing range of the fan 1000 in the gathering mode, and the average wind speed in the blowing range of the fan 1000 in the scattering mode is less than the average wind speed in the blowing range of the fan 1000 in the gathering mode, and the air of the fan 1000 is soft.

[0228] The blowing range of the fan 1000 in the gathering mode is less than the blowing range of the fan 1000 in the scattering mode, and the average wind speed in the blowing range of the fan 1000 in the gathering mode is greater than the average wind speed in the blowing range of the fan 1000 in the scattering mode, and the air of the fan 1000 is strong.

[0229] It should be noted that the "blowing range" refers to the area where the wind speed of the fan 1000 is greater than the rated wind speed (such as 0.4m / s), and the "standard test distance" is three times the diameter of the circle where the plurality of blade tips 311 are located. It can be understood that when simulating and testing the fan 1000, it is not limited to measuring at the above-mentioned "standard test distance", as long as the fan 1000 is measured at the same position.

[0230] As Figure 18 shown, in some embodiments of the utility model, the fan 1000 further comprises an air outlet mesh cover 400, and the air outlet mesh cover 400 is arranged in the air outlet area 220 of the fan 1000.

[0231] Specifically, the air outlet mesh cover 400 is installed on the shell 200, the air outlet 131 of the air duct adjusting piece 130 is opposite to the air outlet mesh cover 400, and the air outlet mesh cover 400 is provided with a mesh structure on the air outlet area 220. Airflow can be discharged through the mesh structure, and at the same time, the air outlet mesh cover 400 can shield the internal structure of the fan 1000, prevent the blade 310 from breaking and flying out through the opening when the fan 1000 is working, and prevent the user from being injured due to accidental touch of the blade 310, thereby improving the safety of the fan 1000, and the air outlet mesh cover 400 can also reduce the accumulation of dust and other sundries in the fan 1000.

[0232] Referring to Figure 18 In some embodiments of the utility model, the air outlet mesh cover 400 includes a middle area 410 and an outer ring area 420, the air guide rib 430 of the middle area 410 is formed as a circular arc rib 431, and the air guide rib 430 of the outer ring area 420 is formed as a straight rib 432.

[0233] Specifically, the middle area 410 and the outer ring area 420 are configured as annular shapes, and the middle area 410 is coaxially arranged with the outer ring area 420, and the outer ring area 420 is sleeved on the outer side of the middle area 410 to realize the zoning design of the air outlet mesh cover 400, which is not only beautiful but also can realize the visualization of the air outlet area 220.

[0234] Further, since the area of the air outlet 131 of the air duct adjusting piece 130 is different in the air diffusion state and the air convergence state, the air outlet area 220 corresponding to the air outlet 131 of the air duct adjusting piece 130 in the air diffusion mode of the fan 1000 is different from the air outlet area 220 corresponding to the fan 1000 in the air convergence mode, when the air duct adjusting piece 130 is in the air convergence state, the air outlet 131 is arranged opposite to the middle area 410, and at the same time, the middle area 410 is opposite to the airflow adjusting piece 120, the middle area 410 of the air outlet mesh cover 400 can further straighten the airflow, further improving the axial component velocity of the airflow, when the air duct adjusting piece 130 is in the air diffusion state, the air outlet 131 is arranged opposite to the outer ring area 420 and the middle area 410 at the same time.

[0235] Further, the air guide rib 430 of the middle area 410 is formed as a circular arc rib 431, and the air guide rib 430 of the outer ring area 420 is formed as a straight rib 432, the circular arc rib 431 can be designed according to the principle of Archimedes spiral, a plurality of circular arc ribs 431 are uniformly and spaced arranged along the circumferential direction, and the protrusion directions of the circular arc ribs 431 are the same, the circular arc rib 431 can effectively reduce the resistance generated by the air guide rib 430 to the airflow, thereby effectively reducing the resistance of the air outlet mesh cover 400 to the airflow.

[0236] When the fan 1000 is in the air convergence mode, the air outlet 131 is arranged opposite to the middle area 410, and after the airflow flows out from the air outlet 131, it flows to the middle area 410, the circular arc rib 431 can play a role in straightening the airflow to convert the circumferential component velocity of the airflow into the axial component velocity, thereby ensuring the convergence effect of the airflow, and can make the air outlet of the fan 1000 more powerful.

[0237] Further, the outer ring area 420 is provided with linear ribs 432 extending in the radial direction, and the linear ribs 432 are uniformly arranged in the axial direction, when the fan 1000 is in the air diffusion mode, the air outlet 131 is arranged opposite to the outer ring area 420 and the middle area 410, the air flow flows out of the air outlet 131 to the outer ring area 420 and the middle area 410, and the linear ribs 432 can keep the air flow in the circumferential direction, thereby ensuring the flow area of the air flow in the radial direction and ensuring the air outlet area of the fan 1000 in the radial direction.

[0238] In some embodiments of the utility model, in the direction away from the first central axis, the air outlet end of the linear rib 432 extends outwardly in the direction away from the rotation center line of the driving fan 300.

[0239] It should be noted that, in the direction in which the linear rib 432 extends, the end of the linear rib 432 away from the support 110 is defined as the air outlet end of the linear rib 432, and the end of the linear rib 432 close to the support 110 is defined as the air inlet end of the linear rib 432.

[0240] Specifically, in the radial direction of the air outlet area 220, the air inlet end of the linear rib 432 is farthest from the rotation center of the driving fan 300, and the air outlet end of the linear rib 432 is closest to the rotation center of the driving fan 300, so that the linear rib 432 is arranged at an angle with the rotation center line of the driving fan 300, the resistance of the linear rib 432 to the air flow is small, the circumferential component velocity of the air flow is maintained, and the air outlet area of the fan 1000 in the radial direction is thus ensured.

[0241] In some embodiments of the utility model, the inclination angle of the linear rib 432 relative to the rotation center line is in the range of 20°-40°.

[0242] Specifically, the inclination angle of the linear rib 432 relative to the rotation center line is in the range of 20°-40°, which can further ensure that the resistance of the linear rib 432 to the air flow is small, the circumferential component velocity of the air flow is maintained, and the air outlet area of the fan 1000 in the radial direction is thus ensured.

[0243] In some embodiments of the utility model, when the air duct adjusting piece 130 is in the air diffusion state, in the direction towards the air outlet 131, the longitudinal section of the air duct adjusting piece 130 extends outwardly in the direction away from the rotation center line of the driving fan 300.

[0244] Specifically, when the air duct adjusting piece 130 is in the air diffusion state, the radial distance between the inner wall of the air duct adjusting piece 130 and the rotation center line of the driving fan 300 gradually increases in the direction towards the air outlet 131, wherein the radial distance between the inner wall of the air duct adjusting piece 130 close to the driving fan 300 and the rotation center line of the driving fan 300 is the smallest, and the radial distance between the inner wall of the air duct adjusting piece 130 far away from the driving fan 300 and the rotation center line of the driving fan 300 is the largest, and the air outlet angle of the air duct adjusting piece 130 in the air diffusion state can be substantially parallel to the straight line rib 432 to reduce the air outlet resistance and maintain the circumferential component velocity of the airflow.

[0245] In some embodiments of the present application, the air outlet mesh cover 400 is detachably arranged in the air outlet area 210 of the fan 1000.
